Recent forecasts from the India Meteorological Department and other models indicate peak temperatures in Lucknow on June 18 around 38–40 °C under partly cloudy skies with isolated thundershowers possible, driven by stalled monsoon progression and persistent pre-monsoon heat across Uttar Pradesh. Strong daytime solar heating combined with limited cloud cover and low soil moisture from below-normal rainfall favors highs near or slightly above seasonal norms, while any convective activity could cap extremes by enhancing mixing or brief cooling. These conditions align with the market’s clustering around 39 °C as the modal outcome, reflecting traders’ assessment of model consensus and typical June variability in the Indo-Gangetic plain rather than outlier heatwave intensification. Updated IMD guidance and afternoon satellite observations on June 17–18 will provide the key inputs for final resolution.
